User manual ROTEL RC-850

[. . . ] Read all the instructions before connecting or operating the component. Heed all warnings and safety information in these instructions and on the product itself. You must allow 10 cm or 4 inches of unobstructed clearance around the unit. Do not place the unit on a bed, sofa, rug, or similar surface that could block the ventilation slots. [. . . ] Please contact your authorized Rotel dealer for answers to any questions you might have. Save the RC-850 shipping carton and all enclosed packing material for future use. Shipping or moving the RC-850 in anything other than the original packing material may result in severe damage to your amplifier. Fill out and send in the owner's registration card packed with the RC-850. It is your best record of the date of purchase, which you will need in the event warranty service is ever required. RC-850 Stereo Control Amplifier 6 Placement Like all audio components that handle low-level signals, the RC-850 can be affected by its environment. We recommend installing the RC-850 in furniture designed to house audio components. Such furniture is designed to reduce or suppress vibration which can adversely affect sound quality. Ask your authorized Rotel dealer for advice about component furniture and proper installation of audio components. Remote Sensor 3 The Remote Sensor is located to the right of the Phones jack on the front panel. It must be clear of obstructions or the remote control will not work properly. The operation of the Remote Sensor can also be affected if it is exposed to bright light, particularly sun light. In addition remote control functions may not work reliably if the batteries in the RR-AT97 are weak. If you are going to be away from home for an extended period of time such as a month-long vacation, it is a sensible precaution to unplug your amplifier (as well as other audio and video components) while you are away. STANDBY Switch 1 Remote OFF/ON Switch STANDBY Indicator 2 A Be sure to keep the power cords, digital signal cables and regular audio signal cables in your installation away from each other. See Figure 2 on page 3. Input Signal Connections e and r [See Figure 3. ] The RC-850 has conventional RCA-type connectors for all inputs. NOTE: To prevent loud noises that neither you nor your speakers will appreciate, make sure the system is turned off when you make any signal connections. Line Level Inputs r The CD, Tuner, and Aux inputs of the RC-850 are "line level" inputs. NOTE: The EXT REM IN jack located next to these jacks is for use with an external IR sensor duplicating the front panel IR sensor and located in the primary zone. 12 Volt Trigger Outlet p 12V Trigger Connections p Many Rotel amplifiers offer the option of turning them on and off using a 12 volt trigger signal sent to them. When the RC-850 is turned on, a 12 volt DC signal is sent to the amplifiers to turn them on. When the RC-850 is put in STANDBY mode, the trigger signal is interrupted and the amplifiers turn off. To use the remote turn on feature, connect one of the RC-850 12V TRIGGER OUT jacks to the 12 volt trigger input of a Rotel amplifier, using a cable with mono 3. 5 mm mini-plugs on both ends. The +12 V DC signal appears at the "tip" connector. Phono Input e and Ground w Connection Some audio components can be turned on automatically when they receive a 12V turn on "signal". Connect the compatible components to the RC-850 with a conventional 1/8" miniplug cable. When the RC-850 is in Standby mode, the trigger signal is interupted, so the components controlled by it are turned off. Plug the cable from the turntable into the appropriate left and right phono inputs. If the turntable has a "ground" wire connect it to the screw terminal to the left of the Phono inputs. It will help prevent hum and noise. IR Inputs and Outputs External Remote Input i This 3. 5 mm mini-jack (labeled EXT REM IN) receives command codes from an industrystandard infrared receivers (Xantech, etc. ) located in the main listening room. [. . . ] If the sound is loud and distorted turn down the volume on the player. If the sound is not loud enough, even when the RC-850 volume control is turned up fairly high, then carefully turn up the volume control on the player. NOTE: When the 3. 5mm (mini jack) is inserted into the Media Player socket the rear input called AUX3 is disconnected. Removing the 3. 5mm plug from the Media player socket will allow the rear AUX3 input to function. The Balance Control adjusts the left-to-right balance of the sound output. [. . . ]
